Dolphin + Wii console homebrews = Failure?

[Luigi__]

When I try to run a Wii console homebrew (for example the template app provided with devkitpro), it just takes forever to load.
If I call any GX_XXXXXXXX function inside the program loop, it loads, but I still see no text on the screen.
Is it just me or Dolphin doesn't like these console homebrews?
